SECTION 3. Administration.

The Plan shall be administered by the Committee. A majority of the Committee shall constitute a quorum, and the acts of the members of the Committee who are present at any meeting thereof at which a quorum is present, or acts unanimously approved by the members of the Committee in writing, shall be the acts of the Committee. Subject to the following and any applicable law, the Committee, in its sole discretion, may delegate any or all of its powers and duties under the Plan, including the power to grant Awards under the Plan, to the Chief Executive Officer of the Company, subject to such limitations on such delegated powers and duties as the Committee may impose, if any. Upon any such delegation all references in the Plan to the “Committee”, other than in Section 8, shall be deemed to include the Chief Executive Officer; provided, however, that such delegation shall not limit the Chief Executive Officer’s right to receive Awards under the Plan. Notwithstanding the foregoing, the Chief Executive Officer may not grant Awards to, or take any action with respect to any Award previously granted to, a person who is an officer subject to Rule 16b-3 or a Director. Subject to the terms of the Plan and applicable law, and in addition to other express powers and authorizations conferred on the Committee by the Plan, the Committee shall have full power and authority to: (i) designate Participants; (ii) determine the type or types of Awards to be granted to a Participant; (iii) determine the number of Units to be covered by Awards; (iv) determine the terms and conditions of any Award; (v) determine whether, to what extent and under what circumstances Awards may be settled, canceled or forfeited; (vi) interpret and administer the Plan and any instrument or agreement relating to an Award made under the Plan; (vii) establish, amend, suspend or waive such rules and regulations and appoint such agents as it shall deem appropriate for the proper administration of the Plan; and (viii) make any other determination and take any other action that the Committee deems necessary or desirable for the administration of the Plan. Unless otherwise expressly provided in the Plan, all designations, determinations, interpretations and other decisions under

or with respect to the Plan or any Award shall be within the sole discretion of the Committee, may be made at any time and shall be final, conclusive and binding upon all Persons, including the Company, the Partnership, any Affiliate, any Participant and any beneficiary of any Award.

SECTION 4. Units.

(a) Units Available. Subject to adjustment as provided in Section 4(c), the number of Units with respect to which Awards may be granted under the Plan is 13,700,000. If any Phantom Unit is forfeited or otherwise terminates or is canceled without the delivery of a Unit, then the Unit covered by such Award, to the extent of such forfeiture, termination or cancellation shall again be Units with respect to which an Award may be granted.

(b) Sources of Units Deliverable Under Awards. Any Units delivered pursuant to an Award shall consist, in whole or in part, of Units acquired in the open market, from any Affiliate, the Partnership or any other Person, or any combination of the foregoing.

(c) Adjustments. In the event that the Committee determines that any distribution (whether in the form of cash, Units, other securities, or other property), recapitalization, split, reverse split, reorganization, merger, consolidation, split-up, spin-off, combination, repurchase, or exchange of Units or other securities of the Partnership, issuance of warrants or other rights to purchase Units or other securities of the Partnership, or other similar transaction or event affects the Units such that an adjustment is determined by the Committee to be appropriate in order to prevent dilution or enlargement of the benefits or potential benefits intended to be made available under the Plan, then the Committee shall, in such manner as it may deem equitable, adjust any or all of (i) the number and type of Units (or other securities or property) with respect to which Awards may be granted and (ii) the number and type of Units (or other securities or property) subject to outstanding Awards or, if deemed appropriate, make provision for a cash payment to the holder of an outstanding Award; provided, that the number of Units subject to any Award shall always be a whole number.

SECTION 5. Eligibility.

Any Employee or Director shall be eligible to be designated a Participant and receive an Award under the Plan.

SECTION 6. Awards.

(a) Phantom Units. The Committee shall have the authority to determine the Employees and Directors to whom Phantom Units shall be granted, the number of Phantom Units to be granted to each such Participant, the Restricted Period, the conditions under which the Phantom Units may become vested or forfeited, which may include, without limitation, the accelerated vesting upon the achievement of specified performance goals, and such other terms and conditions as the Committee may establish with respect to such Awards, including whether DERs are granted with respect to such Phantom Units.

(i) DERs. To the extent provided by the Committee, in its discretion, a grant of Phantom Units may include a tandem DER grant, which may provide that such DERs shall be paid directly to the Participant, be credited to a bookkeeping account (with or without interest in the discretion of the Committee) subject to the same vesting restrictions as the tandem Award, or be subject to such other provisions or restrictions as determined by the Committee in its discretion.

(ii) Forfeiture. Except as otherwise provided in the terms of the Phantom Units grant, upon termination of a Participant’s employment with the Company and its Affiliates or membership on the Board, whichever is applicable, for any reason during the applicable Restricted Period, all Phantom Units shall be forfeited by the Participant. The Committee may, in its discretion, waive in whole or in part such forfeiture with respect to a Participant’s Phantom Units; provided, however, the Participant shall have no right to petition or request the Committee to review, or bring an appeal to the Committee regarding, the forfeiture.

(iii) Lapse of Restrictions. Upon or as soon as reasonably practical following the vesting of each Phantom Unit, subject to the provisions of Section 9(b), the Participant shall be entitled to receive from the Company one Unit or cash equal to the Fair Market Value of a Unit, as determined by the Committee in its discretion.

(b) Performance Awards. The Committee is authorized to grant Performance Awards to Participants on the following terms and conditions:

(i) Right to Payment. A Performance Award shall confer upon Participant rights, valued as determined by the Committee, and payable to the Participant to whom the Performance Award is granted, in whole or in part, as the Committee shall establish at grant or thereafter. The performance criteria and all other terms and conditions of the Performance Award shall be determined by the Committee upon the grant of each Performance Award or thereafter.

(ii) Other Terms. A Performance Award may be denominated or payable in cash, deferred cash, Units, other Awards or other property, and other terms of Performance Awards shall be as determined by the Committee.

(c) General.

(i) Awards May Be Granted Separately or Together. Awards may, in the discretion of the Committee, be granted either alone or in addition to, in tandem with, or in substitution for any other Award granted under the Plan or any award granted under any other plan of the Company or any Affiliate. Awards granted in addition to or in tandem with other Awards or awards granted under any other plan of the Company or any Affiliate may be granted either at the same time as or at a different time from the grant of such other Awards or awards.

(ii) Compliance With Section 409A. Each Award under this Plan is intended either (i) to qualify as “short term deferral” as such phrase is used in Section 409A of the Internal Revenue Code of 1986 or (ii) to comply with the requirements of Section 409A. In that regard, notwithstanding anything in any Award to the contrary, in no event shall payment of or under an Award be made later than 2-1/2 months following the year in which such payment ceases to be subject to substantial risk of forfeiture for purposes of Section 409A.

(iii) Limits on Transfer of Awards. No Award and no right under any such Award may be assigned, alienated, pledged, attached, sold or otherwise transferred or encumbered by a Participant and any such purported assignment, alienation, pledge, attachment, sale, transfer or encumbrance shall be void and unenforceable against the Company or any Affiliate; provided, however, that Awards may be transferred by will and the laws of descent and distribution.

(iv) Term of Awards. The term of each Award shall be for such period as may be determined by the Committee.

(v) Unit Certificates. All certificates for Units or other securities of the Partnership delivered under the Plan pursuant to any Award shall be subject to such stop transfer orders and other restrictions as the Committee may deem advisable under the Plan or the rules, regulations and other requirements of the SEC, any stock exchange upon which such Units or other securities are then listed, and any applicable federal or state laws, and the Committee may cause a legend or legends to be put on any such certificates to make appropriate reference to such restrictions.

(vi) Consideration for Grants. Awards may be granted for such consideration, including services, as the Committee determines.

(vii) Delivery of Units or other Securities. Notwithstanding anything in the Plan or any grant agreement to the contrary, delivery of Units pursuant to vesting of an Award may be deferred for any period during which, in the good faith determination of the Committee, the Company is not reasonably able to obtain Units to deliver pursuant to such Award without violating the rules or regulations of any applicable law or securities exchange. Such payment may be made by such method or methods and in such form or forms as the Committee shall determine.

(viii) Minimum Vesting Provision. Awards (other than cash‑settled Awards) made to Employees or Directors shall not be scheduled to vest earlier than the date that is one year following the date the Award is granted by the Committee; provided, however, that, notwithstanding the foregoing, Awards that result in the issuance of an aggregate of up to 5% of the Units available pursuant to Section 4(a) may be granted to any one or more Employees or Directors without respect to such minimum vesting provision.

SECTION 7. Change in Control.

(a) Change in Control. A “Change in Control” shall be deemed to have occurred upon the occurrence of one or more of the following events: (i) any direct or indirect sale, lease, exchange, liquidation, division or other transfer (in one transaction or a series of related transactions) of all or substantially all of the assets of the Partnership to any person or persons, other than to one or more Affiliates; (ii) the consolidation, reorganization, merger, recapitalization, exchange, division or other similar transaction (in one transaction or a series of related transactions) (any such transaction or series of transactions referred to herein as a “Merger”) pursuant to which (a) more than 50% of the combined voting power of the outstanding equity interests in the Company or its successor entities cease to be owned, directly or indirectly, by the Partnership, (b) more than 50% of the combined voting power of the outstanding equity interests in the Partnership or its successor entities cease to be, directly or indirectly, owned immediately following the Merger by the owners of such interests immediately prior to the Merger, or (c) the Company or one or more other Affiliates of the Partnership cease to be general partner(s) of the Partnership or its successor; (iii) a person or group other than the Partnership or its consolidated subsidiaries directly or indirectly becoming the “beneficial owner” (as defined in Rules 13d-3 and 13d-5 under the Exchange Act) of more than 30% of the voting power of the then outstanding common units of the Partnership or its successor; or (iv) individuals who, as of the date hereof, constitute the Board (the “Incumbent Board”) cease for any reason to constitute at least a majority of the Board or of the board of directors or equivalent body of any successor parent of the Partnership or of the Company; provided, however, that any individual becoming a director subsequent to the date hereof whose election or nomination for election by the Partnership’s unitholders was approved by a vote of at least a majority of the directors then comprising the Incumbent Board in the ordinary course of business shall be considered as though such individual was a member of the Incumbent Board, but excluding, for this purpose, any such individual whose initial assumption of office occurs as a result of an actual or threatened election contest with respect to the election or removal of directors or other actual or threatened solicitation of proxies or consents by or on behalf of a Person other than the Board or otherwise outside the ordinary course of business. A Change in Control shall not be deemed to have occurred as a result of a transaction or series of transactions undertaken solely for the purpose of converting the Partnership from a limited partnership to a c-corporation or limited liability company.

(b) Payout of Awards after Change in Control. If, within two (2) years following a Change in Control, a Participant has a Termination of Affiliation (excluding any transfer to an Affiliate of the Company) voluntarily by the Participant for Good Reason or involuntarily by the Company, the Partnership or an Affiliate thereof (other than due to Cause), Awards granted prior to a Change in Control, shall automatically vest and become payable, in full, and all Restricted Periods shall terminate and all performance criteria, if any, shall be deemed to have been achieved at the maximum level with respect to such Awards. Any payout owed to the Participant pursuant to this section shall be settled in cash.

(c) Notification of Good Reason Event. If, within two (2) years following a Change in Control, a Good Reason Event occurs, the Participant shall provide written notice to the Company not later than 90 days after the occurrence of the Good Reason Event setting forth in reasonable detail the circumstances that constitute the Good Reason Event and tendering his or her resignation for Good Reason. If the Participant does not provide notice as set forth above, the Participant shall not have the right to resign for Good Reason based on any Good Reason Event

occurring more than 90 days before a notice is given. Upon receipt of the Participant’s written notice, the Company shall have 30 days to remedy the Good Reason Event or to notify the Participant of its intent to not remedy the Good Reason Event. If the Company remedies the Good Reason Event within such 30 day period, the Participant’s resignation for Good Reason shall be rescinded and the Company shall have no obligation to pay the amount due pursuant to this section. If the Company (i) does not cure the Good Reason Event within such 30 day period or (ii) provides notice to the Participant of its intent to not remedy the Good Reason Event, the Participant’s resignation shall be effective immediately, and the Company shall be obligated to make payment to the Participant as provided herein.

(d) Definitions. For purposes of this Section 7 only, the following terms shall have the meanings set forth below:

(i) “Cause” means, unless otherwise defined in an Award Agreement, the occurrence of any one or more of the following, as determined in the good faith and reasonable judgment of the Committee: (i) willful failure by a Participant to substantially perform his or her duties (as they existed immediately prior to a Change of Control), other than any such failure resulting from a Disability, or (ii) gross negligence or willful misconduct of the Participant which results in a significantly adverse effect upon the Company, the Partnership, or an Affiliate thereof, or (iii) willful violation or disregard of the code of business conduct or other published policy of the Company, the Partnership, or an Affiliate thereof by the Participant, or (iv) Participant’s conviction of a crime involving an act of fraud, embezzlement, theft, or any other act constituting a felony or causing material harm, financial or otherwise, to the Company, the Partnership, or an Affiliate thereof.

(1) a material change in the Participant’s duties from those assigned to the Participant immediately prior to a Change of Control, unless associated with a bona fide promotion of the Participant and a commensurate increase in the Participant’s compensation, in which case the Participant shall be deemed to consent;

(2) a significant reduction in the authority and responsibility assigned to the Participant;

(3) the removal of the Participant from, or failure to reelect the Participant to, any corporate or similar office of the Company, the Partnership, or an Affiliate thereof to which the Participant may have been elected and was occupying immediately prior to a Change of Control, unless associated with a bona fide promotion of the Participant and a commensurate increase in the Participant’s compensation or in connection with the election or appointment of the Participant to a corresponding or higher office of the Company or any Affiliate, in each which case the Participant shall be deemed to consent;

(4) a reduction of more than 10% of a Participant’s base salary;

(5) termination of any of the incentive compensation plans of the Partnership or the Company in which the Participant shall be participating at the time of a Change of Control, unless such plan is replaced by a successor plan providing incentive opportunities and awards at least as favorable to the Participant as those provided in the plan being terminated;

(6) amendment of any of the incentive compensation plans of the Partnership or the Company in which the Participant shall be participating at the time of a Change of Control so as to

provide for incentive opportunities and awards less favorable to the Participant than those provided in the plan being amended;

(7) failure by the Company, the Partnership, or an Affiliate thereof to continue the Participant as a participant in any of the Company’s or Partnership’s incentive compensation plans in which the Participant is participating immediately prior to a Change of Control on a basis comparable to the basis on which other similarly situated employees participate in such plan;

(8) except in relation to a wage freeze applicable to all employees of the Company, the Partnership, or an Affiliate thereof, modification of the administration of any of the incentive compensation plans so as to adversely affect the level of incentive opportunities or awards actually received by the Participant;

(9) a requirement by the Company, the Partnership, or an Affiliate thereof that the Participant’s principal duties be performed at a location more than fifty (50) miles from the location where the Participant was employed immediately preceding the Change of Control, except for travel reasonably required in the performance of the Participant’s duties;

(10) a signification reduction in the authority, duties or responsibilities of the supervisor to whom the Participant reports, including a requirement that the Participant report to an officer of the Company or employee instead of reporting directly to the board of directors of the Company;

(11) a significant reduction in the budget over which the Participant retains authority; or

(12) any other action or inaction that constitutes a material breach by the Partnership, Company or Affiliate of an agreement, if any, under which the Participant provides services.

SECTION 8. Amendment and Termination.

Except to the extent prohibited by applicable law:

(a) Amendments to the Plan. Except as required by the rules of the principal securities exchange on which the Units are traded and subject to Section 8(b) below, the Board or the Committee may amend, alter, suspend, discontinue or terminate the Plan in any manner, including increasing the number of Units available for Awards under the Plan, without the consent of any partner, Participant, other holder or beneficiary of an Award or other Person.

(b) Amendments to Awards. Subject to Section 8(a), the Committee may waive any conditions or rights under, amend any terms of, or alter any Award theretofore granted, provided (i) the Committee may not reprice the Awards and (ii) no change, other than pursuant to Section 7(c), in any Award shall materially reduce the benefit to Participant without the consent of such Participant.

(c) Adjustment of Awards Upon the Occurrence of Certain Unusual or Nonrecurring Events. Subject to Section 8(b), the Committee is hereby authorized to make adjustments in the terms and conditions of, and the criteria included in, Awards in recognition of unusual or nonrecurring events (including, without limitation, the events described in Section 4(c) of the Plan) affecting the Partnership or the financial statements of the Partnership, or of changes in applicable laws, regulations or accounting principles, whenever the Committee determines that such adjustments are appropriate in order to prevent dilution or enlargement of the benefits or potential benefits intended to be made available under the Plan.

SECTION 9. General Provisions.

(a) No Rights to Award. No Person shall have any claim to be granted any Award under the Plan, and there is no obligation for uniformity of treatment of Participants. The terms and conditions of Awards need not be the same with respect to each recipient.

(b) Withholding. The Company or any Affiliate is authorized to withhold from any Award, from any payment due or transfer made under any Award or from any compensation or other amount owing to a Participant the amount (in cash, Units, other securities, Units that would otherwise be issued pursuant to such Award or other property) of any applicable taxes payable in respect of the grant of an Award, the lapse of restrictions thereon, or any payment or transfer under an Award or under the Plan and to take such other action as may be necessary in the opinion of the Company to satisfy its withholding obligations for the payment of such taxes. In no event shall the withholding for taxes exceed that which is necessary to satisfy the employer’s maximum withholding requirements for the applicable jurisdiction (or such other rate as may be determined by the Company after considering any accounting consequences or costs). Units withheld or tendered for the payment of taxes shall not again be Units with respect to which Awards may be granted.

(c) No Right to Employment. The grant of an Award shall not be construed as giving a Participant the right to be retained in the employ of the Company or any Affiliate or to remain on the Board, as applicable. Further, the Company or an Affiliate may at any time dismiss a Participant from employment, free from any liability or any claim under the Plan, unless otherwise expressly provided in the Plan or in any Award agreement.

(d) Governing Law. The validity, construction, and effect of the Plan and any rules and regulations relating to the Plan shall be determined in accordance with the laws of the State of Delaware law without regard to its conflict of laws principles.

(e) Severability. If any provision of the Plan or any award is or becomes or is deemed to be invalid, illegal or unenforceable in any jurisdiction or as to any Person or Award, or would disqualify the Plan or any award under any law deemed applicable by the Committee, such provision shall be construed or deemed amended to conform to the applicable laws, or if it cannot be construed or deemed amended without, in the determination of the Committee, materially altering the intent of the Plan or the Award, such provision shall be stricken as to such jurisdiction, person or award and the remainder of the Plan and any such Award shall remain in full force and effect.

(f) Other Laws. The Committee may refuse to issue or transfer any Units or other consideration under an Award if, in its sole discretion, it determines that the issuance or transfer or such Units or such other consideration might violate any applicable law or regulation, the rules of the principal securities exchange on which the Units are then traded or entitle the Partnership or an Affiliate to recover the same under Section 16(b) of the Exchange Act.

(g) No Trust or Fund Created. Neither the Plan nor any award shall create or be construed to create a trust or separate fund of any kind or a fiduciary relationship between the Company or any participating Affiliate and a Participant or any other Person. To the extent that any Person acquires a right to receive payments from the Company or any participating Affiliate pursuant to an award, such right shall be no greater than the right of any general unsecured creditor of the Company or any participating Affiliate.

(h) No Fractional Units. No fractional Units shall be issued or delivered pursuant to the Plan or any Award, and the Committee shall determine whether cash, other securities or other property shall be paid or transferred in lieu of any fractional Units or whether such fractional Units or any rights thereto shall be canceled, terminated or otherwise eliminated.

(i) Headings. Headings are given to the Sections and subsections of the Plan solely as a convenience to facilitate reference. Such headings shall not be deemed in any way material or relevant to the construction or interpretation of the Plan or any provision thereof.

(j) Facility Payment. Any amounts payable hereunder to any person under legal disability or who, in the judgment of the Committee, is unable to properly manage his financial affairs, may be paid to the legal representative of such person, or may be applied for the benefit of such person in any manner which the Committee may select, and the Company shall be relieved of any further liability for payment of such amounts.

(k) Gender and Number. Words in the masculine gender shall include the feminine gender, the plural shall include the singular and the singular shall include the plural.

SECTION 10. Term of the Plan.

The Plan shall be effective on the date of its approval by the Board or the Committee and, unless earlier terminated by the Board or the Committee, shall continue until the tenth anniversary of the earlier of (i) the date the Board or Committee adopted the Plan or (ii) the date the Partnership’s unitholders approved the Plan. However, unless otherwise expressly provided in the Plan or in an applicable Award Agreement, any Award granted prior to such termination, and the authority of the Board or the Committee to amend, alter, adjust, suspend, discontinue or terminate any such Award or to waive any conditions or rights under such Award, shall extend beyond such termination date.
